During the Nokia World conference this morning, Nokia unveiled the Lumia 800, its long-awaited Windows Phone 7.5 smartphone. The Lumia 800 features very similar hardware to the MeeGo-powered N9, but there are some different internal components and, of course, that Microsoft operating system.

The quad-band GSM/EDGE, 900/1900/2100MHz 3G/HSPA 14.4 3G-powered Lumia 800 maintains the same striking, injection-molded design as the N9, and it looks just as beautiful in this application. It is created from a single piece of polyurethane that Nokia promises is as durable as it is attractive. It has a 3.7-inch, WVGA ClearBlack AMOLED(INFO) display with a curved front that seamlessly blends into the body of the phone. Powering the Lumia 800 is a single-core, 1.4GHz Qualcomm Snapdragon processor with 512MB of RAM. There is 16GB of internal storage and an 8 megapixel camera with autofocus, dual-LED flash, and a Carl Zeiss f/2.2 lens. Externally, the Lumia 800 differs from its N9 predecessor in that it sports a dedicated camera key, but does not have a front-facing camera. A 1,450mAh battery offers up to 13 hours of talk time or 11 days of standby on 2G.

The Lumia 800 is running Windows Phone 7.5 "Mango," and it is not terribly different from other Windows Phone models that we have seen before. The company did add three new apps to the platform, though: a turn-by-turn navigation app, a streaming music service, and a sports information app. The turn-by-turn navigation is called Nokia Drive and it is an exclusive for Nokia devices. It is the only full, voice-guided navigation app for the platform, and it allows users to download maps to their device for offline use. The Nokia Music app, another exclusive app, offers a streaming feature called MixRadio that lets a user stream music to their phone anywhere they are for free. Users can choose from over 100 stations to listen to, and they can download up to 50 songs to their device for offline listening. The sports app is the result of a partnership with ESPN and Nokia, and offers quick access to scores and news for your favorite teams.

Since Nokia is hoping that many of its existing Symbian smartphone users will be making the switch to its new Windows Phone devices, the company has included a contacts transfer app to help users get all of their friends and family loaded onto their new Mango-powered devices.

The Nokia Lumia 800 measures 116.5mm x 61.2mm x 12.1mm (4.6in x 2.4in x .48) in size and weighs 142g (5.0oz), and will be available in black, cyan, and magenta colors (with color matched soft cover included). The phone will be making its debut next month in the UK, Italy, Spain, France, Germany, and the Netherlands for 420 EUR (US$577). It will launch in additional global markets before the end of the year. A U.S. launch has not been announced, but Nokia said that it has a portfolio of products that will come to the U.S. in 2012.
